Figure 4.19 Illustration of the regular and wideband reference signals for PDCCH [68].

The block of bits b(0),b(1),,b(NPDCCH1)image, where NPDCCHimage denotes the number of bits transmitted on PDCCH, is scrambled prior to modulation, resulting in a block of scrambled bits b˜(0),b˜(1),,b˜(NPDCCH1)image where b˜(i)=[b(i)+c(i)]mod2, in which c(i) is a length-31 ...
